Need help with twin turbo selection
Need help with twin turbo selection how is it going i recently sold my f1a procharger and am wanting to go twin turbo or single turbo route. I have been trying to search up alot of info but cant seem to find any recommendations on turbo size for a 408 ci motor. i am looking to try and make at least 1xxxrwhp.
on another note i have been looking at this a/w intercooler and was wondering if any one has had any experiences with them.

There is a mustang here that is pretty famous for doing so much with so little.
6.0 block with 4" stroke crank. Stock unported 317 heads, stock LS1 intake and throttle body. Mild cam.
Ran an S484 at like 22 lbs. Made over 1000whp and ran 7s in the quarter.

Go for whatever will install easiest in the vehicle.
Although a pair of smaller twins would spool a bit faster than a big single and with it being a manual car, this may matter to you.
How far above/below 1k you really want to make again can have a huge bearing on sizing and whether you want to push a smaller unit hard, or larger units a little easier. Fuel used can also play a part in this too.

6870 as a specific size is the Precision Gen2 units...DBB only and a hefty price tag for someone only wanting 1000hp.

As with the many other dozens of threads, a pair of BW SXE362's would spool well and easily cover his power goals and then some.
Or the slightly larger 364's with the 73mm turbine
At a push if he wanted really fast spool he could drop down to a pair of the SXE257's although they'd be working a bit harder in the 1k range.

See little reason not to use the 0.88, again unless you are using manifolds etc that are divided for a divided housing.
That said, I'm about to try some 0.96 housings on my 364's, although it wont be until the new year before it's going again as probably changing other stuff too. I'm only on a 383.
My 364's have the 68mm turbine wheel
I have zero backpressure issues, if anything it is great. But this is just something I wanted to try. The hole in them is surprisingly larger than the 0.88.
pics enclosed. It's amazing turbos can make so much power squeezing through the little hole inside the turbine housing ! lol
BW dont make the larger housing, it's an AGP housing
